a reflective disc hovering around 300 meters above the ground. The object seemed stay in the same area of the sky, but seemed to wobbble on its axis. I could tell this was happening due to the reflection of the suns rays. As soon as I registered the object as being foreign (after 5 seconds) it just seemed to disappear! The object seemed to be made of a matallic material ie. some kind of metal. The disc did not hover horizontally, it hovered at an angle. There was only one craft. The next day on tv. there was a report of a number of sightings accross London and this is what tiggered my memory of the event. However, I can not be certain of the above date being correct, but it was in July 2000.
